IEC 60335-2-76:2018 deals with the safety of electric fence energizers, the rated voltage of which is not more than 250 V and by means of which fence wires in agricultural, domestic or feral animal control fences and security fences may be electrified or monitored. Examples of electric fence energizers coming within the scope of this standard are: – mains-operated energizers; – battery-operated…

This document specifies dimensions and requirements for the design and functional performance of connectors intended to be used on enteral reservoirs. This document does not specify the dimensions and requirements for the medical devices or accessories that use these connectors. Such requirements are given in particular International Standards for specific medical devices or accessories. NOTE 1…

This document specifies quality levels for imperfections in arc-welded joints in aluminium and its alloys. It applies to material thicknesses above 0,5 mm. Three quality levels are given in order to permit application to a wide range of welded constructions. They are designated by symbols B, C and D. Quality level B corresponds to the highest requirement on the finished weld. The quality levels…

IEC 61755-6-2: 2018 defines the dimensional limits of an optical interface for reference connectors necessary to meet specific requirements for fibre-to-fibre interconnection of non-angled polished multimode reference connectors with cylindrical ferrules intended to be used for attenuation measurements in the field or factory. One grade of reference connector is defined in this document. The…

IEC 62477-2:2018 applies to power electronic converter systems (PECS) and equipment, their components for electronic power conversion and electronic power switching, including the means for their control, protection, monitoring and measurement, such as with the main purpose of converting electric power, with rated system voltages from 1 000 V AC or 1 500 V DC up to 36 kV AC or 54 kV DC. This…

L'IEC 62477-2:2018 s'applique aux matériels et aux systèmes électroniques de conversion de puissance (SECP), à leurs composants pour la conversion de puissance électronique et la commande (ouverture et fermeture) électronique de puissance, y compris les moyens de commande, de protection, de surveillance et de mesure, ayant pour principale fonction la conversion de puissance électrique,…

IEC TR 62240-2:2018(E) describes a process and a method for selecting digital semiconductor microcircuits by ensuring that their lifetime is compatible with the requirements of aerospace, defence and high performance (ADHP) applications (generally in connection with functional environments). Methods and guidelines are provided to assess the long term reliability of COTS semiconductor…

IEC TS 62257-9-5:2018 applies to stand-alone renewable energy products. This document deals essentially with off-grid renewable energy products with batteries and solar modules with DC system voltages not exceeding 35 V and peak power ratings not exceeding 350 W. The tests contained herein are capable in many cases of adequately assessing systems at higher voltages and/or power ratings. This new…
